Abstract

The invention relates to a circuit board, a light-emitting panel and a display device. The circuit board comprises a base material, a metal wiring layer, an insulating layer and a bonding pad unit. The metal wiring layer is arranged on the base material and comprises first metal wires and second metal wires, and the first metal wires and the second metal wires are distributed at intervals throughthe first openings. The insulating layer covers the metal wiring layer and the substrate exposed by the first opening. The bonding pad units are distributed in an array mode and exposed out of the insulating layer, each bonding pad unit comprises a first bonding pad and a second bonding pad which are arranged in pairs, the first bonding pads are connected with the first metal wires, the second bonding pads are connected with the second metal wires, and backflow grooves are formed in the bonding pad units. The embodiment of the invention can be used for controlling the light-emitting element, the light-emitting element is easy to position during surface mounting, the light-emitting element can be effectively prevented from inclining, the stability of connection between the light-emitting element and the circuit board is ensured, and the optical utilization rate is high.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a circuit board, a light-emitting panel and a display device. Background technique [0002] Light emitting elements such as LED (Light Emitting Diode, light emitting diode), mini LED (submillimeter light emitting diode), micro LED (micro light emitting diode) are widely used in the field of lighting and display technology. [0003] In order to better control the light-emitting elements to emit light to realize lighting or display, a circuit board for controlling the light-emitting elements needs to be provided. In the existing circuit boards, due to structural design defects, it is impossible to accurately control the placement of the light-emitting elements during the placement process, and the light-emitting elements are easy to shift and tilt, resulting in the light-emitting elements being easy to fall off and reducing optical utilization.
